GENERAL DESCRIPTION
The
ADV7850
is a high quality, single chip, multiformat video
decoder graphics digitizer with an integrated 4:1 multiplexed
HDMI® receiver.
This multiformat 3D comb filter decoder supports the conversion
of PAL, NTSC, and SECAM standards in the form of a composite
or an S-Video input signal into a HDMI output stream. SCART
and overlay functionality are enabled by the ability of the
ADV7850
to process CVBS and standard definition RGB signals
simultaneously.
The
ADV7850
contains one main component processor (CP)
that processes YPrPb and RGB component formats, including
RGB graphics. The
ADV7850
can operate in quad HDMI and
analog input mode, thus allowing for fast switching between the
analog video inputs and HDMI.
The
ADV7850
supports the decoding of a component RGB/
YPrPb video signal into a HDMI output stream. The support
for component video includes 525i, 625i, 525p, 625p, 720p,
1080i, 1080p, and 1250i standards, as well as many other
SMPTE and HD standards.
The
ADV7850
supports graphics digitization. The
ADV7850
is
capable of digitizing RGB graphics signals from VGA to UXGA
rates and converting them into an HDMI output stream. Internal
EDID RAM is available for one graphics port.
The
ADV7850
incorporates a quad input HDMI-compatible
receiver that supports all HDTV formats up to 3D 1080p 60 Hz
and 2160P 24 Hz.
The
ADV7850
supports full HDCP decryption with internal
key storage. The
ADV7850
features HDCP authentication on all
ports simultaneously. The feature allows fast switching between
HDMI ports. Sync measurements and status monitoring are
also available for all HDMI ports. Each HDMI port has dedi-
cated 5 V detect and hot plug assert pins. The HDMI receiver
ADV7850
also includes an integrated equalizer that ensures robust opera-
tion of the interface with cable lengths up to 30 meters. The HDMI
receiver has advanced audio functionality, such as a mute flag,
that prevents audible extraneous noise in the audio output.
In addition, the HDMI receiver incorporates internal EDID
support, which can be made available in full power, power-
down, and power-off modes. An internal regulator supplies
external EDID memory from the HDMI 5 V signal in power-
off mode.
The
ADV7850
incorporates Xpressview™ fast switching on all
HDMI input ports. Using the Analog Devices, Inc., hardware-
based HDCP engine that minimizes software overhead,
Xpressview technology allows fast switching between any two
HDMI input ports in less than 1 second.
The
ADV7850
offers a flexible audio output port for the audio
data decoded from the HDMI stream. HDMI audio formats,
including super audio CD (SACD) via DSD, DST, and HBR are
supported.
The
ADV7850
also features the single mode audio return
channel (ARC) feature. ARC simplifies cabling by combining
upstream audio capability in a conventional HDMI cable.
The stereo audio ADC converts analog audio inputs and
provides the data to the back end via the HDMI interface. The
stereo audio DAC receives I
2
S data from the back end and
converts it to analog audio output. The audio output is available
as both high impedance and a driven output, which is suitable
for driving headphones directly.
Fabricated in an advanced CMOS process, the
ADV7850
is
provided in a 19 mm × 19 mm, 425-ball, CSP_BGA, surface-
mount, RoHS-compliant package, and is specified over the
−20°C to +70°C temperature range.
